Final answer:
The words behave, rage, and shout are instrumental in setting a tense or potentially chaotic mood in the excerpt, as they reflect tension, strong emotion, and loudness respectively.
Step-by-step explanation:
The words that help create the mood in the excerpt are behave, rage, and shout. These words are indicative of a tone that might be described as tense or perhaps even chaotic, relating to the mood of a scene.Words like behave suggest an expectation of control or decorum that could be under threat, lending a tense atmosphere. The word rage explicitly conveys strong emotion, often associated with violence or turmoil, greatly contributing to the mood.
Lastly, shout implies loudness and potentially conflict or excitement, further intensifying the scene's emotional charge. By contrast, words like head and counted are more neutral and do not contribute significantly to the mood. They do not have strong emotional connotations and thus do not set a tense or chaotic tone in the way that behave, rage, or shout do.
